Flatten nested arrays.
🚨 Notice: Code using node.js >= 11 should use the native Array.flat() method instead. 🚨
npm install array-flatten --save
import { flatten } from "array-flatten";
flatten([1, [2, [3, [4, [5], 6], 7], 8], 9]);
//=> [1, 2, 3, 4, 5, 6, 7, 8, 9]
(function() {
flatten(arguments); //=> [1, 2, 3]
})(1, [2, 3]);MIT
